Just two days after James “Mitch” Waller was killed and another rider seriously injured when they were run down from behind while riding in Laguna Canyon Road near Laguna Beach, word comes of yet another Southern California bicycling fatality.

And like the others, she died after her bike was struck from behind.

According to the Press-Enterprise, 38-year old Lake Elsinore resident Lucia Ruano was riding south on Grand Avenue at Marvella Lane in Lake Elsinore when she was hit by a silver Ford F150 pickup at 8:37 am. She was pronounced dead just 35 minutes later at the Inland Valley Medical Center.

As too often happens with fatal collisions in the Inland area, there’s just too little information in the story to give a clear idea what happened. However, a comment on the Lake Elsinore – Wildomar Patch site offered a second-hand report that the truck was traveling at a high rate of speed, trapping the bike underneath.

And yes, the witness says the victim was wearing a helmet; from the sound of it, it probably didn’t matter.

Depending on exactly where the collision occurred, the driver may have drifted off the roadway, or Ruano may have entered the traffic lane to avoid an obstacle on the shoulder. Or the driver may have hit her while turning onto Marvella.

This is the 42nd bicycling fatality in Southern California this year, and the fourth in Riverside County; that compares to 29 and five, respectively, this time last year. Remarkably, it’s also the fifth cycling fatality in tiny Lake Elsinore, population 53,000, since 2010, and the second on Grand Avenue.

And if that doesn’t indicate a serious problem, I don’t know what does.

Meanwhile, bicycling fatalities are nearly 45% ahead of last year in the seven-county SoCal area just halfway into the year. And this comes as we head into the 4th of July weekend, which is traditionally one of the most dangerous times of year for area bike riders; last year seven cyclists were killed within a week of Independence Day.

According to the Press-Enterprise, CHP officers arrested the driver, 40-year old Lake Elsinore resident Jay Dustin Sorrell, an hour after the collision for investigation of drunken driving and gross vehicular manslaughter.

According to authorities, Sorrell allowed his truck to drift onto the right shoulder, where he hit Ruano’s bike at around 40 mph, killing her.
